Mmm.. That's gonna be annoying to debug because it seems to be working
perfectly on my system and I couldn't break it (even starting from `emacs -Q`).
Are you able to provide a recipe for this error at all?

It should appear briefly the first time before being replaced by the icon.
On subsequent refreshes (assuming `preview-point-progress-indicators` is set to
`'faces`), it won't appear but the face of svg images will dim slightly (not
png ones of course).
To have it always appear, set `preview-point-progress-indicators` to `'icons`.

Yes, I meant killing the buffer. I am not sure why it leaves files on my system
(without preview-point -- which fixes these issues). Here's a minimal recipe I
have, starting from `emacs -Q`, maybe others can test it as well to pin down
the discrepancy.

The file test.tex has

Press C-c C-p C-p, then kill the buffer (or quit emacs). On my system, the
folder `_region_.prv` has a temporary directory with the file `preview.ps`.
